Edge-coloring of the complete graph without any rainbow paths
Thanks a lot! The paper looks very helpful for better understanding of the problem. |

Edge-coloring of the complete graph without any rainbow paths
@Gerhard : For $K_4$, I label the vertices by the elements of $Z_2 \times Z_2$, not $Z_4$. If you use $Z_4$, the edge coloring is not well defined. |

Edge-coloring of the complete graph without any rainbow paths
I think your edge coloring may not be well-defined. For instance, the difference between two vertices (0,1) and (0,2) is either (0,1) or (0,5) in $Z_2 \times Z_6$? For $Z_{2^k}$, we don't have such a problem since $x-y = y-x = x+y$. |

Does this poset have a unique minimal element?
@ARupinski : I understand. Thanks for the great question. It was really fun to work on it. We are actually thinking about publishing it if our solution is indeed new. |
